Abstract:
Electric field intensity and ion current density at the ground level of HVDC power lines are significant electrical environment parameters in relation to biological effects. These quantities, largely, depend on the line geometry and meteorological conditions. In. order to make a reliable predetermination of the electric field intensity and ion current density, the paper presents detailed numerical assessment of these quantities on a full scale line.. The governing equations are solved using an iterative algorithm. Factors influencing the ionized field quantities, namely, the wind speed, the line sag, the conductor surface gradient, are accounted for both individually and collectively and the interactions between them is established. Results and discussion are presented.
